WINDOW-SCREEN.

SBCIFICATION forming partof LettersAPatent No. 316,517, dated April 28, 1885. Application filed September 2G, 1884. (No model.)

T @ZZ whom it may concern:

Be it known that I. WILLIAM BATEMA, of

l Athe city and county of San Francisco and State of California, have invented an Improvement `in Window-Screens; and I hereby declare the following to be a full, clear, and exact descrip- Vtion thereof.

.My invention relates to that class of window-screens in which the screen material is i mounted above or below in the window-cas- Varo ing, whereby when the sash is opened the screen unwinds and covers the open space, and when closed it winds up out of the way.

My invention consists in a cord of any suitable nature attached at one end'to la pulley on the winding drum or roller of the screen, and thence passing to and around a suitably-located guide-pulley and to the window-sash, to which it is secured, whereby the movement of the sash operates the winding drum or roller, as I shall hereinafter fully explain by reference to the accompanying drawings,in which- Figure 1 is a front elevation of a window, showing my invention. Fig. 2 is a vertical transverse section. Fig. 3 is a portion of a horizontal section. Fig. 4. is a detail showing pulley H. Fig. 5 is a perspective view showing the course of the cord in the bead.

The object of my invention is to provide a simple and effective window-screen, easily adjusted to place, and perfect in operation.

A is the window-casing, having the glazed sashes B B', upper and lower, respectively, adapted by means of the usual cords and weights to move up and down between the outside and inside beads, C C', and partingstrip D in the ordinary manner.

Let into the top of the window-casing in any suitable manner, as by the box E, is a roller or drum, F, upon which the screen G is adapted to wind and unwind. `The lower end of screen G is secured to the top of the upper sash, B, in a suitable manner, whereby when said'sash is lowered the screen is unwound from its roller and covers the opening; but it is evident that some means must be provided to wind up the screen again as the sash is pushed up. It has been customary to accomthese are liable to get out of order, besidesbeing somewhat expensive and difficult to adjust. By my invention the upward movement of the sash itself produces the desired effect. l

Upon the end of the roller or drum Fis a pulley, H, to which a cord', I, is attached. This cord may be of any suitable material, and of a strength and durability sufficient for the purpose. I 4.. 'i

In the inner face of the outside bead, C, next to the pulley-stile, is cut a groove,`c,Y andln its inner side, next to the side of the sash', lis made another groove, c', Fig. 5. Arecessci, is cut in the inner face of the bead C fatnthe bottom of groove c and at aV point below-fthe lowermost limit of the top of the sash B1@ fIii this recess is mounted a guide-pulley,"Jl,lib"y means of a screw, j, driven into the pulleystile of the window-casing. The cord I passes down inthe groove c from pulley H to, under, and around pulley J, thence into the groove c and up to the top of the sash B, to which it is attached, as shown. W'hen the sash is moved up, the end of cord I is carried up with it, thus drawing on said cord and causing it to rotate yplish this result by springs and weightsjjloii't 'PATENI trios..Y

the roller or drum F, .whereby the screen G is y wound up as the sash is raised.

I do :not confine myself to the exact location of the guide-pulley J, herein shown, nor to the location of the screen-operating cord, for they may be differently placed; but I regard the arrangement shown as being practical and neat,

as it removes them from sight and from danger of injury. To gain access to them t-he bead C has only to be removed.

Although I have described the screen G in connection with the upper sash alone, it is obvious that it can be placed in connection with the lower sash as well by mounting a screenroller in the bottom of the casing, and placing pulleys and a cord in connection with said roller and sash in the same relative positions as those described.

The pulley H on the roller I make by means of a disk, h, separated from the roller end by a short tube, h', and united by a tapering pin, h2, as shown. In this way I make a pulley adapted to receive considerable cord. y Having thus described my invention, what ICO I claim asnew, and desire to secure by Letters Patent, is-1. y 1 f 1. In a Window having a screen attached to its sliding sash and adapted to be unwound 5 from a roller or drum by the movement of said sash in opening, the means by which thescreell is wound up -as thel sash is' closed, consisting of a cord attached to the roller or drum and to the sliding sash, substantially as .herei-n dero scribed.

2. The sliding sash of a Window, the roller or drum mounted in the casing, and the screen G on said rollerv and 'connected'with the sash,

in combination with the means by which saidl:

i 5 roller is rotated to Wind up the screen as the sash closes,- consisting of a cord attached at one Y .errdto and adapted to rotate the drum, and at.

ethe other to the Window-sash, said cord being Isuitably guided in its course between its endzo connections, substantially as herein described.

,. 3. The windowsash B, roller Fin thetop ofthe window-casing, and vscreen G on said` roller and attached to the sash, in combination iwith. the means by which ythe screen is Woundf ,-25 up as the sash is raised, consisting of the pul'l leyH on. the -roller, the guide-pulley J below,

gandthecordI, attached to pulley H, passing .under and around. pulley J and. up tothe sash 4.1. The window-sash B, roller .F in. the top;

B, toQWh'ich it issecured, substantially as heref lthe Window-casing, and the screen G on said ,roller and-attachedto the sash, in combination 1 With the' means by whichu the screen is Wound f il'p-asjthe sash` is raised, consisting of the pul- 55 ley H on the roller, the guide-pulley J in a recess, c2, in the inner face of the bead C, and the cord I, attached to pulley H, passing down yin a groove, c, made in the inner face of bead C, t0 and around said guide-pulley J, and up 4o in a groove, c', made in the inner side of the bead to the sash B, to which it is secured, substantially as herein described.

5.` In a Window having a screen attached tol its sliding sash and adapted to be unwound 45 4from relier or drum by the movement of said sash in opening, the cord I and pulleys H J, by which said screen is Wound up as the sash. is closed, in combination Withthe bead `G, having groovesccand recess c2, for receiving-the 5u Vcord I andgpulley J, whereby they'areconcealed, substantially as herein described. 6. Inga window having a screen attachedfto its.. sliding sash and to a Winding roller-oi" drum, as described, the combinationl of said ,roller or drum With the pulley H on its end,

.formed of a disk, h,separated from the roller end by a. tube, h', and secured by a tapering- `pin, h?, substantiallyas and for the purpose -herein described.
